Embrace DC2T network architecture-"China IC Micro column" 2016.8.10

recently seenW3techstheHttp/2and theIPv6statistics on usage, see table below. ActuallyHttp/2This standard has been granted for only two years, and all globalWebsite over9%has adopted aHttp/2. You may remember,IPv6in1998years have been approved. But it's fair to say that until2006yearsIcannApprove distributedIPv6address Policy,IPv6only formally into business, so we should actuallyIPv6from2006starting from the beginning of the year. Even so,IPv6have also been10years, and to this day, only about6%website to start using. Even if we only see the world before1000Big website,Http/2and theIPv6The use ratio is also basically the same, are about20%.

Application Layer ( layer 7)HTTP/2 This standard takes two years to reach a network layer (L3) Standard IPv6 a decade of usage .

This may be followed by a general rule that is "not bad and not repaired" and IPV4 address has not been exhausted, everyone is first mixed. But I think this represents a new trend, and today's network is starting to differentiate into two separate areas: the Flow production network and the Traffic transport network .

The typical enterprise application scenario is to transport the traffic generated by a large number of applications to the destination safely and at high speed. Although companies vary in their industry, region and size, the number of applications and delivery details will vary, but most large and medium-sized enterprises (more than five employees) have deployed more than a few different applications . Network Department said the pressure of Alexander, because the application of demand is the business needs, can not meet the application will affect the company's performance. Even if we migrate most of our applications to the public cloud, the network department is not out of this pressure, because employees still have to access these applications, access to the application will require the network, network quality or by the network Department to control.

However, the challenges of application are not only so, but also a matter of annoyance. Today, it's not just cloud computing that moves applications to the cloud, but also the evolving architecture of applications, including Docker,DevOps, and so on that are sweeping the application development community. Of course, how to quickly deploy an ever-increasing number of mobile applications, and the associated technologies are changing. These changes have brought great pressure on the network, which demands the network security and reliability, and the network has enough expansibility and elasticity, and the pressure of the network department is increasing .

This is why we see the separation of two layers of network, one is responsible for the core business network, that is, traffic transport network, the second is responsible for the application of scale expansion and security network, that is, traffic production network. The two-tier network work together to ensure that the core business is supported for security and reliability, and facilitates rapid expansion and secure delivery of new applications and APIs. A data center that embraces two tiers of network architecture will be better able to ensure security without restricting business development, as applications and APIs can be built to the new business requirements, with the latest architecture, quickly responding to business needs and gaining market opportunity.

in fact, this stratification can also be seen as "north-South" traffic and "things" traffic. The core network (north-south) is responsible for transporting traffic to and from the data center. This is where the most front-line defenses are deployed, where firewalls,DDoS protection, and various gateways, including secure (HTTPS) and plaintext (HTTP) Web traffic are converted gateways, mobile protocol gateways between API and back-end service gateways, IoT devices, and control applications. This is the traditional network combat territory, also become netops, characterized by less change, meticulous management, either manual management, or programmatically drive management. The core network has a high reliability requirement because one of the core network errors is not affecting 1-2 applications, but all the business of the entire enterprise. This is why traditional networks do not like change, strict management, but also criticized as a rigid network.

In- depth data centers are applications and users that generate traffic and transport traffic through the core (north-south) network. Applications are surrounded by new technologies such as virtual machines and containers, and virtual machine technology has been widely adopted as one of the main drivers of enterprise-class cloud computing, with containers (including Docker) driving the architectural revolution in enterprise applications, which are important components of the application network. It also includes traditional servers and applications. New applications are constantly evolving, new features are emerging, and new architectures are being deployed, increasing the frequency of deployment and driving the rapid growth of business and productivity. The new Application network (also known as the Traffic production network) is resilient and is a software-defined network that is automatically managed by programming tools and frameworks. Application network has jumped out of the NetOps era, into the DevOps domain, the application network developers and operators will avoid the core business network changes, to ensure the stability of the core business network. It is expected that the application network will have errors, and errors are common, but people will not be so anxious, because the application of network failures only affect one or several applications, will not affect the overall enterprise.

DC2T Network Architecture (DataCenter 2-tier network Architecture, data center two-tier networking architecture) is a key to embracing cloud computing andDevOps trends, without the innovation of network architecture Cloud computing andDevOps will be blocked. access to internal and external applications requires a high level of reliability, scalability, and security for core network support. But applications and users areat the heart of the cloud, DevOps era, and to deliver your applications quickly, you will undoubtedly need to build flexible, software-driven infrastructures (including networks). dc2t Network Architecture emerged, just meet the Cloud,the DevOps era of the new network needs, the two-tier network is not either, but must wing, together to support new applications and users.

North-South Network (core network) is the responsibility of carrying traffic, reliable, safe is the key. Things to the network (application Network) responsible for production flow, need and application of close cooperation, elasticity, security is the key. By constructing dc2t network Architecture, we can help enterprises to meet the network challenges of the cloud era successfully.
